Definitions
- This invention relates to a process and apparatus for the distillation of aqueous liquids and is particularly useful in the distillation of sea water to produce fresh water.
- the stripping means includes a pressure gradient being provided along the direction of hot feed flow in chamber 20, the pressure decreasing from inlet 24 to outlet 26.
- the cross-sectional dimensions of chamber 20 can be selected in regard to the desired volumetric flow rate of the hot feed through chamber 20 and the capacity of pump 22 chosen to provide the desired pressure gradient.
- means are provided in channel 20 to provide additional turbulence and mixing in the flowing hot feed, such as by spacer 50 shown in Figure 1 B.
- Spacer 50 includes an interconnected network of longitudinal strands 52 and transverse strands 54.
- Longitudinal strands 52 serve to separate membrane 16 and wall 18, so as to provide flow spaces for the feed in chamber 20, while strands 54 serve to position strands 52.
- Transverse strands 54 are considerably smaller in diameter than strands 52. The reduced size of strands 54 is necessary to allow the formation of collection chamber 14 by deformation of membrane 16 while simultaneously increasing the turbulence along chamber 20.
- the dimensions of spacer 50 should be selected not to unduly increase the pressure gradient as an overall decrease in efficiency could result due to the necessity for increased pumping power and thickness of condensor sheet 12 to withstand any static pressure imbalance between chambers 20 and 30.
